With his skilled steering of JPMorgan Chase through the financial crisis, calm demeanor, and deferential behavior -- Dimon hasn't rankled legislators who are trying to clean up the
banking industry, and he was one of the few heavyweight banking CEOs who didn't blow off a high-profile meeting with Obama in December -- you might assume he would escape the
blogosphere's wrath.

Unfortunately, in the populist eye, Dimon is guilty by association, with just a 50% positive score, according to Zeta Interactive, on par with former AIG chief Liddy.

How it was done: Zeta's technology mines the online media landscape -- including millions of blogs, message boards, and social media posts -- and then uses algorithms to measure
both the volume and tone of conversations about a given subject -- in this case, the CEOs of Fortune 500 companies. Rankings are based on the percentage of total chatter about a
given CEO that is qualified as positive.
